2 Claims.

This invention appertains to new and useful improvements in means for extruding or crushing fruits, vegetables and other substances.

The principal object of the present invention is to provide an apparatus for crushing fruits, vegetables and other articles to the end that they will be crushed in such a manner as not to be mushy or sticky in consistency, but rather of a mealy nature.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the apparatus.

Figure 2 is a front elevational view.

Figure 3 is a vertical section on a line 3-3 of Figure 2.

Figure 4 is a vertical sectional view on a line 4-4 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a frame which consists of the horizontal frame structure made up of the side members B6 and end members 1-1. Leg members 8 depend from the corners of this frame. A pair of posts 99 rise from the intermediate portions of the side members 6 and are braced by the inclined beams ID.

A roll is mounted at the lower portion of the post, while a second complementary roll I2 is mounted at the upper portion of the post. A shaft 13 is journalled through the lower portions of the posts 9 and carries the aforementioned roll II. One end of this shaft I3 is equipped with the pulley l4 over which the belt l5 from the pulley 16 on the armature shaft of the drive motor I! is trained. I

The upper end portions of the posts 9 are formed with longitudinally extending slots IS in which the bearing blocks H] are slidably disposed. From each of the blocks [9 extends a threaded shank 20, extending upwardly through a bore 2| in the corresponding post 9 to project above the upper edge of the corresponding post.

Said threaded shank is equipped with an adjusting nut 22.

Journalled through the blocks I9 is the shaft 23 carrying the roll 12.

The perforate belt 24 is trained over the rolls II and I2 as shown in Figure 1.

Numeral 25 denotes the hopper which has a vertical side wall 26 and the inclined side wall 21. This hopper is secured by suitable means 28 to the posts 9. The discharge end 29 is located immediately over the trough 3U defined by the meeting of the outside flight of the belt 24 with the roll II. A straight side 26 of the hopper is in very close proximity with the outside flight of the belt.

As shown in Figure 3, an agitator 3| is provided in the lower portion of the hopper 25 and consists of the shaft 32 having a plurality of cross pins 33 projecting therefrom. One end of this shaft 32 extends laterally of the hopper 25 and is equipped with a pulley 34. A belt 35 is trained over the pulley 34 and a pulley on the remaining end of the shaft I3, is denoted by numeral 36. Thus the agitator 3| is obtained from the roll shaft l3, While the latter shaft obtains its power from the motor l1.

Numeral 38 denotes a horizontal self-conveyor which is trained over the pulley 39 on one pair of legs 8. The conveyor 38 serves to carry away material which has passed through the belt and dropped downwardly.

Numeral 40 denotes an elongated clearer member mounted across the side members 6 of the frame 5 for clearing the outside of the belt 24 of material extruding.

It can be seen that the hopper 25 is charged with the fruit or vegetables to be extruded. The agitator 3| keeps the articles from jamming in the hopper. The articles drop from the hopper into the trough-like space 30 and are squeezed by the roll H through the perforations of the belt 24.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of theinvention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. An extruding apparatus comprising a pair of uprights in horizontally spaced relation, upper and lower shafts between the uprights, rolls on the shafts, an endless perforated web trained over the rolls, a hopper mounted between the uprights and between the flights of the web, and agitating means in the hopper, one side of the hopper being slanted and the other side being disposed vertically and in closed spaced relation with one flight of the web.

2. An extruding apparatus comprising a pair of vertically disposed and horizontally spaced uprights, a pair of vertically spaced and horizontally disposed rolls interposed between the uprights, an endless perforated web trained over the rolls, a hopper interposed between the upmaterial discharged therefrom to the convergent rights and being secured thereto, said hopper area between one flight of the web and the lower having a vertical side wall and a slanting opporoll, the vertical side of the hopper being in close site wall, said slanting wall terminating in close parallel relation with respect to the said one spaced relation with respect to the said vertical 5 flight of the web.
